3.7i cannot be biamped.
I agree that Mac gear can be bettered.
I use my old 4B-SST² with my new Magnepan 20.7s.
(Just got them.)
When I can again afford a big spend I may get the Bryston 7B3 as, Bryston is the #1 recommended amp to pair with Magnepan.
Sorry I have no experience with the amps the op is interested in.
I mainly posted to brag about my speakers, and mention the 3.7i cannot be biamped (nor can the 20.7)
